The preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a rear end elevationof a wagon, showing the application of the invention thereto. Fig. 2 is a longitudinal section through the wagon and attachment. is a vertical transverse sectionthrough the frame of the, attachment on the line `3 3 of Fig. 4 is a detail view of the device f' Fig. 2. for supporting andadjusting ,the elevator.

Fig; 5 is a detail view of the main drive-shaft and ldrum thereon.' Figs. 6 and 7 are detail views of supporting-brackets. Fig. 8 isa section through thewheeled baseof the attachment; and Fig. 9 is a horizontal transverse section on line 9 9 of Fig. 1 throughthe attachment and sides of the wagon-body', the gearing being omitted.

Referring now more particularly to the drawings, the numeral 1 designates a wagon box or body of the type customarily employed for transporting grain and other similar materials. The attachment is adapted for application to the rear end of this bed or box and Vcomprises a drag or wheeled frame 2, composed of a relatively stationary section-3 and an adjustable section 4, said sections being provided attheir outer ends with side pieces 5 to overlap the sides of the wagonbody and provided with hooks 6 or like fastening devices to engage eyes 7 on the body to detachably secure the attachment thereto. Any other suitable means for securing the attachment in-position may, however, be employed. The section 4 ofthe frame is mounted at its upper and lower ends in channeled guides 8 and 9, fixed to the section 3, so that it may be adjusted to regulate the width of the frame for-application to wagon-boxes of Fig. 3

ries set-screws 12c to ock the standards 12. thereto in adjusted position.

provid ed with a horizontal extension 10, pro-VA jecting beneaththe -section 4 to a point beyond the outer` edge of said section 4 and the adjacent side of the Wagon, said extension being of boxformation to form a chamber or hopper 1 1 to receive the material forced from the box 1. Standards 12 project downward from the opposite ends ofthe horizontal or tion 10 .and carry supportingwheels o r ro 1ers i different widths. The frame member 3 is 13 at .their lower ends, which rollers sustain the weight of the frame 2 when the device is. v

applied tothe wagon-box and 'also permit saidiframe to be trundled towardthe wagonbox for application thereto and awayfrom the box for removal afterthelOady has beendischarged. The wheels 13 are journaled'upona supporting-bracket 12a, having sockets or y passages 12b tofslidably receivesaid, Stand,

The lower open end of the frame 2,2 of the elevator, is arrangedA in open.- communication. with the outlet end of thehop er 11 and is ivotally supported upona. shaft 23, carried `by brackets 2 4, iixedto the ho per, and arranged in said frame is an lend ess conveyervv 25, provided with conveyer-buckets 26,; adapted to receive the material discharged! from the buckets 15 and convey thesame to conveyer 25 is suitably supported at its IIO yto

charges into the hopper 11. of the upper cables 33I are res ectively atu'piper end and asses at its lower end -around a rum'on the s aft 23, which carries a pinion 23, connected by a belt or chain 23i with a s rocket-pinion 16a on the shaft 16', carrying t e drum 16, whereby motion will be communicated from the conveyer 14 to the elevator 25, as will bereadily understood. The

elevator-frame is provided upon one side with a bracket 28having a screw-threaded bore or socket to receive the voutei` screwthreaded end of a supporting and adjusting rod 29, having' a fastening member 30 at its inner end to pivotally enga e a suitable fastening member 31 on the a jacent side of the Wagon-box and provided at its outer end with a crank-handle 31- This rod su ports the elevator and ermits the saine lto lie adjusted toward an from the Wagon-box and to regulate the hei ht of its discharge end, as will be readily un erstood. Arranged within the wagon-box is a load-discharge device or feeder comprising a follower 32, to the up er and lower portions of "which are attac ed pairs of draft-cables 33 and 34, which extend at their rear ends through openings in the sections 3 and 4 of the frame 1. The follower 32 is normally arranged at the front end f the Wagon-body and is adapted to be drawn rearwardly b means acting upon the cables 33 and 34 tov orce the 'load'toward the rear end of the wagon-body, where it dis- The rear ends tached to winding-drums 35 an' 35', ixedly mounted upon' shafts 36 and 36,journaled at their outer ends in brackets 37, res ectively,

1 carried by the frame-sections 3 an 4. The' shaft 36 is olygonal in form or feathered to vfit and 4sli e within the correspondinglyshaped tubular shaft 36, thus forming a telescopic shaft which is adjustable with the sections 3 and 4. The rear ends ofl the cables -34 are similarly attached to drums 38 and 38 upon similarly-constructed shafts -39 39', journaled in brackets 40 on the frame-sections. The shaft 38 is adapted to be operated by a sprocket-chain 41, engaging a sprocket-wheel 42 on said shaft an so engaging a sprocket-wheel 42', mounted upon a short shaft journaled upon a bracket `43, fixed to the wall of thel base or horizontalextension 10, on which short shaft is also a.

beveled pinion 44, meshing with a corrersppnding pinion 45 on thevdrive-sliaft 18.

e shaft 39'communicatesvmotion to the shaft 39f, which is connected by a sprocketch-ain l464 and sprocket-gears. 47 and 48 with the shaft 36', whereby4 the u per and lower shafts will be simultaneous y o rated to Wind up the cables '33 and 34 an draw the follower 32 rearwardly.

In operation the end-gate is removed from the wagon wlfen the latter reaches the oint where the load is to be discharged an the loading device applied, after *which thel ends of the cables 33 and 34 are attached to their respective winding-drums and the elevator adjusted, if necessary. The apparatus is then operated by means of the hand-crank 19 and motion transmitted to the follower and conveyers to discharge and elevate the Inaterial to the delivery-point. After the Wagon has been unloaded the device may be detached and ap lied to a succeeding Wagon, and so on. It wi l thus be seen that the invention provides a simple 'and convenient form of a paratus which may be attached for unloa ing urposes to a Wagon and that by means o the adjustable sections 3 and 4 the frame may be applied to wagons of different Widths. j

Having thus described the invention, what is claimed as new is 1. An unloading attachment for wagons comprising a frame adapted to be attached to ried by said frame, means r operating said conveying mechanism, a follower o erative in the wagon-body to feed the loa to said conveying mechanism, and means actuated by the operating mechanism of the conveyer for moving the follower.
